One of the most powerful features of a modern computer system is the ability to store data in a form which can be easily retrieved and transported or copied across to other computer systems or media. Data created and accessed by a user in the computer is stored in what is called a file. This concept of an electronic file to store electronic data mimics the physical world usage of a file to store data written on paper. This mimicry is carried further by the organization of these electronic files into electronic folders or directories. Like a physical folder, an electronic folder can contain very many files. A folder may also have sub-folders or sub-directories.
Note:
We shall be using the terms folder and directory interchangeably, unless stated otherwise.

Files and folders can be created, copied, moved (i.e. transferred) and deleted. The folders themselves are organized in a hierarchical manner starting at the root of the file system. Each user is given a home directory and upon logging in, the user is placed in his home directory.
